Who is Fawkes?

Fawkes as you should know (well at least I hope you know) is 
Dumbledore's (DD) phoenix. I have heard many rumors stating 
Fawkes is DD's brother. Just as Sirius can change to a dog, 
DD's brother is able to change into a phoenix. After DD's 
death, Fawkes is suddenly gone-perhaps to look for the 
horcruxes or maybe he is going to the actually alive DD? 
My beliefs on this rumor are still quesey (I have no idea 
what my opinion is!). If you have any ideas or clues post.

Thanks,
